Robotically controlled convertible display

ABSTRACT

A convertible display includes a number of video display panels which are movable between a first position in which the panels extend in the same plane to define a unified display and a configuration in which one or more of the panels are moved into other planes which allow them to form steps. Multiple of the rotated panels may form a sequence of steps, e.g. a staircase. The convertible display may be moved via a robotic mount, whereby the position or orientation of the convertible display may be changed.

FIELD OF THE INVENTION

The present invention relates to entertainment elements and the movementof entertainment elements.

BACKGROUND OF THE INVENTION

A wide variety of devices are used for entertainment purposes. Forexample, electronic displays are now extremely common and are utilizedin a variety of environments. Such displays were initially usedprimarily in television sets and were later used with computers.Initially, these displays were primarily CRT type displays which werelarge and bulky.

In recent years, other display technologies have been developed. Plasma,LCD, LED and other types of displays are now commercially producible inlarge display sizes. At the same time, however, these displays aregenerally thin, thus taking up much less space than CRT type displaysoffering the same display area.

As such, these displays are now utilized for a variety of purposes. Forexample, large displays are used at stadiums to present replays ofsporting events. These types of displays are also sometimes mounted towalls in stores to present advertising information.

In order to attract attention to advertising, graphic information may bepresented on the displays. This information may comprise excitingpatterns, such as in bright colors, flashing effects and the like, todraw attention to the display. Still, these displays may be overlookedand advertisers and other users of these displays continue to seek newways to use these displays and increase their viewership.

Other types of entertainment devices may be used in other settings. Forexample, in a theatrical production, large props may be located on astage. The props may be moved into various positions to create differentscenes and various actions. The props are often moved manually, such aswith ropes and pulleys, limiting the situations where they may be usedor their effectiveness.

To move some props, ladders or stepping stools may be required. Further,ladders and stepping stools or grounded staircases could be usedthemselves as props.

SUMMARY OF THE INVENTION

The invention comprises moveable entertainment elements and methods ofmoving one or more entertainment elements.

One embodiment of the invention is a robotic mount. The robotic mount isconfigured to support one or more entertainment elements and move theone or more entertainment elements in at least two dimensions ordirections, and preferably in three-dimensions/three-dimensional space.In one embodiment, the robotic mount comprises a base and a movablesupport. The base supports the display support, such as by resting upona support surface or by connection to a support, such as a wall or otherelement.

The moveable support is preferably movable in three dimensions ordirections, whereby one more entertainment elements connected theretoare so movable. In one embodiment, the moveable support comprises aplurality of members which are movably connected to one another in onemore directions/dimensions. The moveable support may comprise, forexample, a robotic arm having a base, a main support which is rotatablerelative to the base, a lower arm which is rotatable relative to themain support, an upper arm which is rotatable relative to the lower arm,and a head to which the one or more entertainment elements areconnected, the head movable relative to the upper arm.

In one embodiment, means are provided for moving the moveable support.Preferably, the means permits the moveable mount to be automated in thesense that it can be moved without direct physical contact by a humantherewith. This means may comprise one or more electric motors or thelike.

One aspect of the invention is a robotically controlled electronicdisplay. The robotically controlled electronic display preferablycomprises a robotic mount which supports and moves one or moreelectronic displays. The electronic displays may comprise, for example,flat panel electronic video displays.

In another embodiment of the invention, a unitary display may comprisetwo or more individual displays. One or more robotic mounts may beutilized to move one or more or all of the displays of the unitarydisplay. For example, each display of a unitary display comprising aplurality of displays may be associated with its own robotic mount, thuspermitting all of the displays of the unitary display to be movedindependently and/or synchronously.

Another aspect of the invention comprises a robotically controlled videoprojector. The robotically controlled video projector comprises arobotic mount which support and moves one or more video projectors. Thevideo projectors may comprise, for example, CRT or DLP type electronicvideo projectors. The robotic mount may move the one or more projectorsto cause then to display information, images, moving images or the likeupon various display surfaces such as screens, walls or floors.

Yet another aspect of the invention comprises a robotically controlledstaircase. The robotically controlled staircase comprises a roboticmount which supports and moves a staircase. The staircase preferablydefines one or more steps from a bottom end to a top end. The roboticmount is preferably configured to move the staircase inthree-dimensional space, such as from ground level to one or more raisedplatforms.

A further aspect of the invention comprises a convertible display thatcan function as both an electronic video display and a staircase. Theconvertible display comprises a plurality of sub-display elements orpanels that in one position function as elements of an electronicdisplay and are thus positioned planar and adjacent to one another toform a contiguous video display. When functioning as a staircase, one ormore of the sub-display elements or panels are moved (such as byrotation) to a position in which they extend outwardly at an angle whichallows faces or surfaces of the sub-display elements to be used assupporting surfaces, such as steps or stairs. In one embodiment, theposition of the entire convertible display is changeable, such as via arobotic mount which supports the convertible display. The robotic mountis preferably configured to move the convertible display inthree-dimensional space to provide the same uses as those intended for aunitary display or robotically controlled staircase.

One embodiment of the invention is a system including a robotic mountand a controller. The controller may be configured to accept input froma user and/or run control programs for generating instructions or outputsignals which may be used to control the robotic mount and itsassociated entertainment element (such as its associated videodisplay(s), video projector(s), staircase, or a convertible display). Inone embodiment, such a controller may also be configured to controlinformation displayed by the one or more video displays or videoprojectors, including synchronizing the movement thereof with the imagesdisplayed thereby.

FIG. 1 illustrates a robotically controlled electronic display 20 inaccordance with an embodiment of the invention. As illustrated, therobotically controlled electronic display 20 comprises at least oneelectronic display 22 and a robotic or moveable display mount 24. In apreferred embodiment, the electronic display 22 is a thin-panel typedisplay, such as an LCD, LED, plasma or similar display (whether nowknown or later developed). In one embodiment, the electronic display 22has a front or viewing side 25 and an opposing rear side 26. Theelectronic display 22 has a peripheral edge 28.

In one embodiment, the electronic display 22 is generally rectangular inshape, but the display 22 may have a variety of shapes. The electronicdisplay 22 may have a display area at the front side 25, which displayarea is enclosed by a bezel, frame or the like. The display areacomprises the portion of the electronic display 22 which is capable ofdisplaying information.

In a preferred embodiment, the electronic display 22 is relativelylarge, such as for viewing by person situation remotely there from. Theelectronic display 22 may be 20 inches in diagonal size (of displayarea), more preferably at least 36 inches in diagonal size, and evenmore preferably a least 50-60 inches or more in diagonal size. Theelectronic display 22 might comprise a single electronic video displayor more than one display (such as two or more displays which are closelylocated or joined together). The electronic display 22 may be of varioustypes such as CRT, LED, LCD, plasma, etc. and may include touch-screenfeatures, such an overlying touch-sensitive screen.

The electronic display 22 is supported by the robotic mount 24. In apreferred embodiment, the robotic display mount 24 is moveable, thuspermitting the position of the electronic display 22 to be changed. Asdetailed below, in a preferred embodiment, the position of theelectronic display 22 can be changed freely anywhere inthree-dimensional space (not merely one or two dimensions, but in fullthree dimensional space).

In a preferred embodiment, the robotic mount 24 is referred to as“robotic” because it is a device which can change positions withoutdirect manual input. In particular, the robotic mount is preferablycapable of multiple movements without manual intervention (i.e. movebetween various positions based upon a sequence of instructions withouteach movement being prompted by individual user input). Preferably, therobotic mount comprises a robot or robotic arm which can change theposition of the display in at least two (2), and preferably three (3),dimensions or directions.

FIG. 1 illustrated one embodiment of a robotic mount 24. In oneembodiment, the robotic mount 24 comprises a base and a display support.The base is configured to connect or support the display mount andassociated display to a support, and the display support is preferablymovable relative to the base, thus permitting an associated display tobe movable relative to the base and the associated support.

Referring to FIG. 1, the base 30 [not labeled in Fig.] may have avariety of configurations, including various shapes and sizes. Ingeneral, the base 30 is configured to be mounted to or supported by asupport surface, such as a wall, floor or other support, such as aportion of another object. The base 30 may have a generally planarbottom or lower surface for engaging a generally planar support surface,or may have other configurations for engaging support surfaces of othershapes. In one embodiment, the base 30 may include one or more aperturesfor accepting fasteners which are placed into engagement with thesupport surface, for securing the base 30 in a fixed position bytemporarily or permanently connecting the base 30 to that surface.

In a preferred embodiment, a movable support is positioned between thebase 30 and the electronic display 22. This support is preferablymoveable in at least two (2), and more preferably three (3), dimensions.By two or three-dimensions it is preferably meant the standard Cartesiantwo or three-dimensional space, such that the support is capable ofmoving the display about, or relative to, at least two of an x, a y anda z axis. In a preferred embodiment, movement is permitted in all threedimensions. As disclosed below, the robotic mount 24 may permitredundant movement in one or more directions. For example, the roboticmount 24 may include two or more elements which permit it to be moved inthe x, y and/or z direction, or to rotate about the x, y and/or z axis.

As illustrated, in one embodiment, the robotic arm includes a mainsupport 32. In one embodiment, the main support 32 is mounted forrotation relative to the base 30, i.e. about the y-axis as illustratedin FIG. 1. The main support 32 may be mounted, for example, on a bearingsupported shaft which is connected to the base 30, or by other means.

In one embodiment, a lower arm 34 is rotatably mounted to the mainsupport 32. As illustrated, the main support 32 has a first portionmounted to the base 30 and a second portion to which the lower arm 34 ismounted. In a preferred embodiment, the lower arm 34 is rotatablymounted to the main support 32 about a shaft or other mount. In theconfiguration illustrated, the lower arm 34 is mounted for rotationabout a z-axis (i.e. an axis which is generally perpendicular to theaxis about which the base 30 rotates).

As further illustrated, an upper arm 36 is rotatably mounted to thelower arm 34. In one embodiment, a first or distal portion of the lowerarm 34 is mounted to the main support 32, and the upper arm 36 ismounted to a top or proximal portion of the lower arm 34. In oneembodiment, the upper arm 36 is also mounted for rotation about the zaxis.

In one embodiment, a head 38 is located at a distal portion of the upperarm 36. Preferably, the display 25 is mounted to the mount 24 via thehead 38. In one embodiment, the head 38 is mounted for rotation relativeto the upper arm 36 (and thus the remainder of the mount 24). In oneconfiguration, a first portion 40 of the head 38 is mounted for rotationabout an x axis relative to the upper arm 36 (i.e., about an axis whichis perpendicular to both the y and z axes, and thus about an axis whichis generally perpendicular to the axis about which the main support 32and upper and lower arms 36, 34 rotate).

Further, in the embodiment illustrated, a second portion 42 of the head38 is mounted for rotation relative to the first portion 40 and theupper arm 36, about the z-axis. As illustrated, the display 22 ismounted to the second portion 42 of the head 38.

The various portions of the mount 24 may be connected to one another ina variety of fashions. For example, the various portions may beconnected to one another via a shaft and bearing mount, where the shaftis connected to one component and engages one or more bearings supportedby the other component, such that the shaft may move relative to thebearing(s), thus permitting the components to move relative to oneanother. The portions of the mount 24 might be mounted to one another inother fashions, however, such as by hinged mounting or the like.

Preferably, the mount 24 includes means for moving the one or moreportions thereof, and thus the display 22 connected thereto. Asillustrated, the mount 24 may include one or more motors M for movingthe components thereof. The motors M may be electrical motors. In otherembodiments, hydraulics or other means may be utilized to move one ormore of the components of the mount 24. For example, a hydraulic armmight be utilized to move the upper arm 36 relative to the lower arm 34in an up and down direction.

In one embodiment, the display 22 may be detachably connected to themount 24, such as to permit the display 22 to be changed or serviced.The display 22 might be connected to a supporting frame, for example.That frame might then be connected to the mount 24, such as byconnecting the frame to the head 38 with one or more fasteners.

As indicated, in a preferred embodiment, the mount 24 is configured tomove the display 22 in three-dimensions, or combinations thereof. Theparticular configuration of the mount 24 may vary for accomplishing thistask. For example, while the mount 24 described above is redundant inits capacity to move in certain directions (i.e. the upper and lowerarms 36, 34 are both configured to move about the z axis), the mount 24could be configured in other fashions (such as by having only a singleportion configured to move in each direction). It will also beappreciated that the number of members or elements which the displaymount comprises may vary. For example, the display mount might comprisea base and a head which is mounted to the based, such as via a swivel,permitting the head to be moved in at least two dimensions. Variousconfigurations of members may also be utilized to effect movement invarious directions. For example, aside from swivels or the rotatingconnections of the display mount illustrated in FIG. 1, members may beconfigured to telescope, slide or otherwise move linearly (i.e. movealong an axis rather than about an axis), or be configured to move alongpaths other than curved paths. For example, the mount 24 may beconfigured to move about the “x” axis, such as to permit the display tobe tilted up and down, to move about the “y” axis, such as to permit thedisplay to be swiveled from side to side, and to simply move along the“z” axis, such as to permit the display to be moved in and out (such astowards or away from a wall/viewer).

In the embodiment illustrated, a single display 22 is connected to asingle mount 24. In another embodiment of the invention, referring toFIG. 2, a unitary display 122 may comprise a plurality of individual orindependent displays 22 located in proximity to one another. In oneembodiment, one or more of those individual displays 22 may be mountedto a mount 24, and thus be configured for movement.

Two or more robotic mounts 24 may be used with one another. FIG. 2illustrates one embodiment of a unitary display 122 comprising nine (9)displays 22. All nine displays 22 are preferably mounted to anassociated mount (not shown). In this manner, each of the nine displays22 may be moved by their associated mount.

FIG. 2 illustrates the displays 22 in an orientation where they arelocated adjacent to one another in a matrix, and in a common plane. Inthe configuration illustrated, there is a central display surrounded bytop, bottom, side and corner displays.

The displays 22 may be moved, however, to other locations and thus otherorientations or positions relative to one another. For example, FIG. 3illustrates the displays 22 in a flower configuration where the top,bottom and side displays are tilted forward relative to the plane whichcontains the central display. The corner displays are rotated and thensimilarly tilted inwardly. In this configuration, the displays arepositioned like the slightly closed pedals of a rose or other flower.

FIG. 4 illustrates the displays 22 again arranged in a matrix and in asingle plane. However, in this configuration, the displays 22 have allbeen rotated 90 degrees, so that the unitary display 122 is taller thanwider.

In one embodiment, each display 22 of the unitary display 122 has anassociated robotic mount. In this manner, each display 22 may be movedindependently of the other. In another embodiment, multiple displays maybe coupled to or otherwise associated with a single mount (such thatgroups of displays are movable together). In yet another embodiment, oneor more of the displays 22 may be fixed and others may be connected to amount 24 for movement.

In one embodiment, means may be provided for controlling a single mount(such as illustrated in FIG. 1) or one or more or all of a plurality ofmounts associated with a unitary display (such as illustrated in FIG.2). In one embodiment, one or more mounts may be controlled by acontroller. The controller might comprise, for example, anelectronically or mechanically operated controller.

In a preferred embodiment, the controller may comprise or include acomputing device. Various instructions may be provided from thecontroller to the one or more robots/robotic mounts, causing therobots/robotic mounts to move. For example, a user might provide aninput to the controller, which input is a request to move a particulardisplay from a first to a second position. The controller may generateone more signals or instructions which are transmitted to the requiredmount for causing the mount to so move the display. The signal mightcomprise opening of a switch which allows electricity to flow to one ormore motors for a predetermined period time which is necessary for themotor to effect the desired movement. In another embodiment, the signalmight comprise an instruction which is received by sub-controller of themount, which sub-controller then causes the mount to move as desired.

In one embodiment, the controller may be configured to cause a singlemount or multiple mounts to move in various patterns or other desireddirections. For example, the controller might be programmed to cause thedisplays to move in a particular pattern. Referring to FIGS. 2-4, forexample, the controller may be configured to move the displays from theposition illustrated in FIG. 2 to that illustrated in FIG. 3 or 4, orvice versa. The controller may be custom-programmed or might beconfigured to execute pre-set sequences of movement. For example, thedisplays may be configured to move at certain times, into certainpositions or in certain patterns, to move with music or the like (suchmusic might be presented via speakers associated with the display or viaa separate sound system or the like).

In one embodiment, the controller may include a processing unit capableof executing machine readable code or “software. As indicated, thatsoftware may comprise a set of instructions which, when executed, causethe controller to move one or more displays in a predetermined motion orpattern, randomly or otherwise. The software might also or insteadsimply comprise a set of instructions which permits a user to providemanual input to cause a display or displays to move, either in directresponse thereto or to generate a programmed movement (which may beimplemented immediately or be stored for implementation at a latertime).

The controller might communicate with the robotic mount via wired orwireless communications. For example, the controller might comprise adesk-top computer running a control program. The desk-top computer mighttransmit signals via a RS-232 communication link including a wiredpathway to the motor or controller of the robotic mount. Alternatively,the desk-top computer and display mount controller might both includewireless transceivers. In this manner, the controller and roboticmount(s) may be located remotely from one another. The same computermight output images or a video feed to the one or more displays.

In one embodiment, video information may be transmitted to the displayor displays either independently of control instructions or dependentlytherewith. For example, the controller may be configured to bothgenerate display information and/or transmit display information to thedisplays, and control the mounts. The controller might be configured tomove the mounts/displays based upon the information which is displayedby the one or more displays. In one embodiment, the one or more displaysmay be moved synchronously with information displayed by the displays.For example, the displays might be moved synchronously with imagesdisplayed by the displays or with music or other accompanyinginformation.

The invention has numerous advantages. One aspect of the invention is amovable display. The display may preferably be moved in three-dimensions(i.e. about three axes which are all perpendicular to one another). Inone embodiment, the display is mounted to a display mount having adisplay support which is movable in three dimensions. Preferably, meansare provided for automatically or remotely moving the display. Asindicated, this may comprise changing the position of one or moreportions of the robotic mount.

One aspect of the invention is a method of remotely or automaticallychanging the position of a display. For example, a display may bemounted to a wall or ceiling in a public area and the position of thatdisplay may be changed at various times in an automatic fashion (asopposed to manual manner, where the position is changed by a personphysically moving the display or its associated mount). This has theadvantage that the position of a display may be moved for variouspurposes, such as for entertainment, for optimizing viewing angle, fordirecting information to viewers in certain locations or areas, or forother reasons. The display might also be mounted to a wall of a home andbe controlled by a user to change the viewing position of the display.

Another embodiment of the invention is a robotically controlledprojector 120. FIG. 5 illustrates one embodiment of a roboticallycontrolled projector 120. Preferably, the robotically controlledprojector 120 comprises at least one projector 122 and at least onerobotic mount 124. The projector 122 may be of a variety of types nowknown or later developed. Preferably, the projector 120 is configured toproject one or more images or a sequence of images (video) onto one ormore surfaces. For example, the projector 120 might comprise a digitallight processing (“DLP”) projector, a CRT, LCD, or other type ofprojector. In one embodiment, the robotically controlled projector 120includes a single projector. However, as illustrated, it might include anumber of projectors 122 a, 122 b, etc.

The robotic mount 124 preferably comprises a robot or robotic armsimilar to that described above and will thus not be described hereinagain in detail. In particular, the robotic mount 124 is configured tomove the at least one projector 122 in at least two (2), and preferablythree (3) dimensions. As also indicated above, the roboticallycontrolled projector 120 may also include a controller. The controllermay be configured to cause the projector 122 to display images or videoat certain times, and may be configured to cause the robotic mount 124to move the projector 122, such as in certain paths.

The projector 122 is preferably mounted to the robotic mount 124. Themount 124 may be used to move the projector 122, thus causing theprojector 122 to display images or video at various locations. Forexample, a robotically controlled projector 120 might be located in alobby and be used to display various information or images upon a screenor another projection surface such as a wall, a floor or the like. Therobotically controlled projector 120 might be used in a theater toproject background images or the like.

It will be appreciated that, like the robotically controlled displaydescribed above, more than one robotically controlled projector 120might be used in tandem. For example, two robotically controlledprojectors 120 might each have a single projector 122. The tworobotically controlled projectors 120 may be configured to move invarious patterns together or independent of one another, such as to showjoint images, synchronous images or the like.

Of course, various other of the features of the robotically controlleddisplay 20 described above may be applied to the robotically controlledprojector 120.

Yet another embodiment of the invention comprises a roboticallycontrolled staircase 220. FIGS. 6 and 7 illustrate a roboticallycontrolled staircase 220. The robotically controlled staircase 220comprises a staircase 222 and a robot or robotic mount 224 which isconfigured to move the staircase 222.

The staircase 222 may have various configurations. In one embodiment,the staircase 222 comprises a supporting body or structure 226. Thestaircase 222 preferably includes a plurality of steps 228. Each step228 may comprise a riser 230 and a landing 232. Each riser 230preferably extends generally vertically upward. The number of steps 228,and thus the number of risers 230, may vary. Preferably, there is atleast one step 228. More preferably, however, there are a plurality ofsteps 228. The depth of each landing 232 and the height of each riser230 may be configured to conform to local building or other codes.

Preferably, the staircase 222 has a first or bottom end 234 and a secondor top end 236. The top end 236 is preferably higher than the bottom end234. The total change in elevation is dependent upon the number of steps228 and the height of the risers 230. The staircase 222 may be straightor it might be spiral, have one or more bends or the like.

In one embodiment, the staircase 222 may be configured to mate with oneor more other elements or structures. For example, the staircase 222 maybe configured to dock or mate to a supporting platform (not shown). Tothis end, the top end 236 and bottom end 234 of the staircase 222 mayend or terminate in a landing 232. This allows the top and bottom ends236,234 to rest upon a supporting surface or platform at generally thesame elevation thereof. In one embodiment, the landing at the top end236 and/or bottom end 234 of the staircase 222 may be larger than thestep landings 232. For example, each of the top and bottom end landingsmay be sufficiently large to permit one more persons to easily standthereon (whereas the step landings are primarily configured to permit auser to simply step thereon as they climb the staircase).

In one embodiment, the staircase 222 may include other features. Forexample, the staircase 222 may include one or more handrails (notshown). The staircase 222 has a width between opposing sides. This widthmay vary, such as being 36 or 48 inches, for example. A handrail may belocated at each side of the staircase to prevent a user from falling offof the staircase and to provide support to users. Likewise, the landing232 at the top end 236 and bottom end 234 of the staircase 222 mayinclude an enclosure. Such an enclosure may be selectively opened andclosed to permit ingress to and egress from the staircase, but preventsuch during movement of the staircase. Such an enclosure might comprisea rail, a chain, or the like. For example, a swinging gate may belocated at both the top and bottom ends 236,234 of the staircase 222 tocontrol ingress to and egress from the staircase 222.

In one embodiment, the body 226 of the staircase 222 might comprise asuperstructure which supports the steps 228. For example, the body 226might comprise a metal framework. The steps 228 might be constructedfrom wood and be supported by that framework. In another embodiment, thebody 226 might define the steps 228. For example, the staircase 222might be constructed from metal, such as step elements which are weldedto one another to form a unitary structure.

The mount 224 preferably comprises a robot or robotic arm similar tothat described above and will thus not be described herein again indetail (for example, such may comprise a base and a moveable support, asdetailed above). In particular, the mount 224 is configured to move thestaircase 222 in at least two (2), and preferably three (3) dimensions.As also indicated above, the robotically controlled staircase 220 mayalso include a controller to move the staircase 222 in certain paths.

As best illustrated in FIG. 7, the staircase 222 is preferably mountedto the mount 224. As illustrated, an adaptor 240 may be used to connectthe staircase 222 and the robotic mount 224. The adaptor 240 may havevarious configurations. FIG. 7 illustrates one configuration in whichthe adaptor 240 engages a bottom portion of one or more of the steps228. However, the adaptor 240 could have other configurations, such asdepending upon the configuration of the staircase 222, including thebody 226 or supporting structure thereof.

As illustrated in FIG. 6, the robotic mount 224 is configured to movethe staircase 222 between various positions. For example, the roboticmount 224 may move the staircase 222 into a position in which its bottomend 234 is positioned on the ground. A user may then step onto thestaircase 222 from the ground, such as by stepping onto a lower landing232 thereof.

The robotic mount 224 may then be used to move the staircase 222, andthe user standing thereon, to another location. In the preferredembodiment where the robotic mount 224 can move in three dimensions, thestaircase 222 may be moved to various positions in three-dimensionalspace which vary from an initial or starting position. FIG. 6illustrates one simplistic embodiment where the staircase 222 is movedin two dimensions: upwardly and forwardly. In this example, thestaircase 222 may be moved upwardly and forwardly, such as to dock witha raised platform 262. A user might then disembark from the staircase222 onto the platform 262.

It will be appreciated that a user may climb up and down the steps 228of the staircase 222 both while the staircase 222 is stationary and/orwhile it is moving. For example, a user might board the staircase 222 atthe bottom end 234 while it is stationary. As the staircase begins tomove to a destination, the user might climb the steps 228 to the top end236 of the staircase 222 to disembark the staircase 222 at thedestination.

The robotically controlled staircase 220 might be used in variousmanners. For example, it might be used in a theater. In such anenvironment a singer might be transported from stage level to a platformwell above stage, or from one location to another over a barrier such asa moat. The robotically controlled staircase 220 might also be used asan amusement ride. In such an embodiment, patrons might board thestaircase 220 as a ride and be transported from one location to another.In one preferred embodiment, a haunted house ride might include one ormore platforms in various locations. The platforms might lead to doorsor other points of entry. Patrons might board the staircase and betransported to one or more of those platforms where they disembark totravel into other portions of the haunted house. In one embodiment, thestaircase might move between various locations before stopping, thusproviding substantial anticipation to the riders as to their finaldestination. It is also possible for there to be more than onerobotically controlled staircase 220. The various staircases 220 mightmove independently between various locations. They might also move sothat they join together at certain times (forming longer staircases toconnect to various locations, for example) or independently at othertimes). As yet another example, a first robotically controlled staircase220 might be used to move patrons from ground level to one or moreplatforms at a first level (above ground) and then a second roboticallycontrolled staircase 220 might be used to move patrons from the firstlevel to an even higher second level (or higher).

As indicated, one or more controllers may be used to control therobotically controlled staircase 220, such as to cause it to movebetween various locations. The patterns of movement may change overtime. For example, in a haunted house ride, the robotically controlledstaircase 220 might be configured to move a first set of riders fromground level to a first platform. However, the robotically controlledstaircase 220 might be configured to move a second set of riders fromthat same ground level to a second, different platform.

Of course, the robotically controlled staircase 220 might be configuredto move between various locations other than ground level and variousplatforms. The robotically controlled staircase 220 may include variousof the other features detailed herein. For example, the roboticallycontrolled staircase 220 may be controlled by one or more controllers,such as to move in certain patterns or paths, including synchronouslywith other elements. For example, the robotically controlled staircase220 may be moved synchronously with music which is being played or withimages that are being displayed.

Yet another embodiment of the invention comprises a convertible displaythat can function as both/either an electronic display and a staircase,and a robotically controlled or movable convertible display. FIGS. 8 and9 illustrate one embodiment of a convertible display. The convertibledisplay comprises a plurality of sub-display elements or panels302(a)-302(m) which cooperate to form a unified electronic display 302.In a preferred embodiment, the sub-display elements or panels302(a)-302(m) are connected to and supported by at least one supportpanel 304 or other supporting structure. The support panel 304 providesstructural support for the electronic display 302 and, when the supportpanel 304 is associated with a robotic mount, provides an interface orconnection between the electronic display 302 and such a robot orrobotic mount 324.

Any number of sub-displays elements or panels 302(a)-302(m) can make upthe electronic display 302. Each sub-display 302(a)-302(m) need notfully extend across the electronic display 302 in one direction as shownin FIG. 8. The sub-display elements 302(a)-302(m) may be apportionedequally or non-equally across the given direction in fractional unitsand the electronic display 302 need not comprise the same fractionalunits at each position of a sub-display element along the orthogonaldirection. Further, it is conceivable that the width of the sub-displayelements 302(a)-302(m) may vary at different locations along theorthogonal direction. Thus, the sub-display elements 302(a)-302(m) maytake on various shapes and sizes across the electronic display 302 andmay preferably, but need not, maintain relative alignment with thesupport panel. As will become apparent, the shapes of the sub-displayelements 302(a)-302(m) are only limited in shape by their functionalityof being usable in forming a staircase or steps to allow a person toascend and descend thereon. However, in a preferred embodiment, theshape of the support panel 304 and the plurality of sub-display elements302(a)-302(m) thereon is rectangular; similar in that regard to mostflat screen video displays currently existing in the art (for example,in other embodiments, the unified display could have a triangular shapein which each sub-display element or panel 302(a)-302(m) is generallytrapezoidal in shape, with the width of each successively higher panelbeing linearly smaller).

In an embodiment where the convertible display is associated with arobotic mount, the mount 324 preferably comprises a robot or robotic armsimilar to that described for the mount 124 used with the electronicdisplay 25 of FIG. 1 and further referenced for the mount 224 used withthe staircase 228 shown in FIG. 6 and will thus not be described hereinagain in detail (for example, such may comprise a base and a moveablesupport, as detailed above). In particular, the mount 324 is configuredto move the convertible display in at least two (2), and preferablythree (3) dimensions. As also indicated above, the roboticallycontrolled convertible display may also include a controller to move theconvertible display in certain paths and to position the electroniccontroller in certain orientations (which controller may also be used tosynchronize movement of the display 302 with content which is displayedon the display, including relative to converting the display between itsdisplay and staircase configurations as described below).

The head 326 shown in FIG. 9 is used to connect the convertible display302 to the mount 224. The head 326 may have various configurations,including a configuration similar to that described above for the head38 attachment to the electronic display 22 of FIG. 1. The convertibledisplay 302 preferably utilizes the support panel 304 to support themultiple sub-display elements 302(a)-302(m), thus preferably causing theattachment point to be the rear side of the support panel 304. Thus, thehead 326 is preferably attached to the support panel 304 (and may beattached in a variety of ways using various fasteners, including throughthe use of hardened steel bolts, screws, rivets, or any other knownfastening devices or mechanisms), between the head 326 and the supportpanel 304. Preferably, if a singular attachment point (including anattachment face having multiple fasteners associated therewith) is used,the head 326 is attached to the support panel 304 in alignment with thecenter of gravity (CG) of the convertible display for optimum stability.In an alternative embodiment, the head 326 may comprise a plurality ofattachment points (or attachment faces) with the mid-point between thembeing the CG point. This would spread the load, accordingly, between themultiple attachment points.

Referring to FIG. 10, the convertible display possesses the dual purposeand capability of functioning both as a display and as steps or astaircase 402 to allow a person 404 to ascend and descend thereon. Inone embodiment, the convertible display may thus function as either anelectronic display 302 or a staircase 402. In a preferred embodiment,the sub-display elements or panels 302(a)-302(m) (or at least a displayor front face thereof) are positioned flat (or parallel or flush withthe support panel 304) when the electronic display 302 is intended tofunction as a display (with each face 306 of the sub-display element inthe same plane as all of the other sub-display elements).

As shown in FIG. 11, when the convertible display is intended tofunction as a staircase 402, one or more of the sub-display elements orpanels 302(a)-302(m) are rotated outwardly 406 from the support panel304 so that they extend into different planes (which planes are atangles relative to the original or display plane).

Preferably, the mount 324 allows for the movement of the convertibledisplay along and/or about, three axes. When the functional purpose ofthe convertible display is to function as an electronic display 302, theconvertible display can be positioned, accordingly, through the motionof the mount 324 in any number of orientations for the intended purpose.If the functional purpose is to perform as a staircase 402, then themount 324 can at another moment in time be re-positioned to the same ora different orientation that is appropriate for the use of the staircase402.

Most importantly, one or more sub-display elements 302(a)-302(m) aremovable between a first position and a second position, such as by anarrangement or mounting of the sub-display elements 302(a)-302(m) and adrive, such as one or more means for moving.

One example of a mounting for the sub-display elements 302(a)-302(m)will be described with reference to FIG. 12. FIG. 12 illustrates anenlarged view of a portion of the convertible display. In this position,all of the sub-display elements 302(a)-302(m) (or at least the frontdisplay faces thereof) generally extend in the same plane, preferablybeing oriented flat or parallel to the support panel 304. In a preferredembodiment, each sub-display element 302(a)-302(m) is attached to an Lbracket 502 on both lengthwise ends of the sub-display elements302(a)-302(m) (only one end shown). Each of the sub-display elements302(a)-302(m) are attached at attachment point 506 along one end fromthe vertex through one of the faces of the L bracket 502 to securely andimmovably support the sub-display element 302(a)-302(m) and atattachment point 508 coinciding substantially with the vertex of the Lbracket 502. Attachment between the L bracket 502 and sub-displayelements 302(a)-302(m) may be through any fastener comprising a bolt,screw, rivet, metallic bonding, glue or other means of attachment knownto those skilled in the art. A third attachment point 510 of the Lbracket attaches substantially at the other end from the vertex to anactuator rod 512. The actuator rod 512 is of sufficient length to extendfrom the actuator rod's origin of actuation to the attachment point 510of the furthest sub-display element 302(a)-302(m). Each of the Lbrackets 504 of the sub-display elements 302(a)-302(m) are securelyattached to the actuator rod 512 so that the linear motion of theactuator rod translates the motion to the L bracket 504 at theattachment point 510. In a preferred embodiment, at least two (2)actuator rods 512 would provide actuation at least at both sides of theconvertible display to translate linear motion to all of the L brackets504 simultaneously and uniformly at both ends of the sub-displayelements 302(a)-302(m).

The actuator mechanism 514 shown in FIG. 12 translates the rotationalmotion of a means for moving 516 to linear motion of the actuator rod512. Although a wheel and axle type actuator mechanism is depicted inFIG. 13 (such as may be implemented by an electric motor having arotating output shaft), other types of means for moving/actuation can beused, including pneumatic, hydraulic, electro-mechanical, other forms ofmechanical devices, such as linear or cam or screw-type actuators, andthe like. Further, one or more motor driven devices may cause each ofthe sub-display elements 302(a)-302(m) to rotate to the respectivepositions. When in operation, the actuator wheel 516 is put intorotational motion 518 causing the actuator rod 512 to move in thedirection of the actuator mechanism 514. The L bracket 502, though heldsecurely in position for linear motion in relation to the actuator rod512, maintains the ability for rotational motion about attachment point510. Linear motion of the actuator rod 512 upon activation of theactuator mechanism 514 causes the L bracket 502 to move towards actuatormechanism 514 from the pulling force exerted at attachment point 510.Support 522 attached to the L bracket 502 at attachment point 508 andaffixed to the support panel 504 secures the L bracket 502 at attachmentpoint 508, preventing linear motion while maintaining the ability toprovide rotational motion about attachment point 508. As actuator rod512 is in motion, the L bracket 502 rotates about attachment point 510and about attachment point 508 causing sub-display elements302(a)-302(m) to rotate away from the support panel 304 with the Lbracket to an angle shown at 524. The actuator rod 512 and sub-displayelements 302(a)-302(m) may be locked in place through a lockingmechanism (not shown), or via locking of the means for moving/driveelement, to prevent the L brackets 504 and sub-display elements302(a)-302(m) from rotating beyond the angle 524 or collapsing backtowards the original position. The angle 524 is preferably selected incombination with the position of the support surface 304 so that a stepsurface 526 (comprising the face of one or more of the sub-displayelements or panels 302(a)-302(m)), is maintained parallel to the floorfor ease of ascent and descent. Adjustments in angle 524 are madethrough the actuator mechanism 514 and thus the degree of translationalmotion of the actuator rod 512. If the mount 324 rested on a surface orfloor angled to the ground, the angle 524 need not be maintainedparallel to the floor but could be adjusted to through the actuatormechanism 514 to ensure the step 526 is maintained parallel to theground or otherwise generally horizontal.

Means for locking actuator mechanisms 514 are well known and may be usedto lock the actuator rod 512 and sub-display elements 302(a)-302(m) inthe desired electronic display 302 or staircase 402 position. Methodsand devices of locking the rotational hinge 520 in place may also beused to assist in or to singularly lock sub-display elements302(a)-302(m) in the electronic display 302 and staircase 402 positions.The locking mechanism may include a definite or indefinite number ofrigid locking points to allow the angle between the sub-display elements302(a)-302(m) and support panel 304 to vary. Detent mechanisms and othermechanical lock and release mechanisms may be used in association withrotational locking hinge 520 to adjust the angular position of thesub-display elements 302(a)-302(m). Such mechanisms may be furthercontrolled by an electronic controller which sends instructions tolocking mechanism to lock the sub-display elements in place once aspecified amount of rotational travel has been reached. In otherembodiments, locking may be achieved by locking or fixing the drivemechanism, such as the drive motor.

The presently discussed embodiment has been described as pulling theactuator rod 512 towards the actuator mechanism 514. In anotherembodiment, the actuator mechanism could push the actuator rod from theopposite end shown in FIG. 12 and FIG. 13 to achieve the same result.

When the convertible display is in its electronic display 302configuration, it can assume any of the features and characteristics ofthe singularly functional electronic display 25 describe above and shownin FIG. 1, and possess any of the same advantages. Similarly, when theconvertible display is in its staircase configuration 402, it can assumeany of the features and characteristics of the staircase 222 describedabove and shown in FIG. 6, and possess any of the same advantages.

To operate, the electronic display 302 receives a video input signal.Each of the sub-display elements 302(a)-302(m) displays imageinformation or graphics. The image information may be the same, but in apreferred embodiment the sub-display elements 302(a)-302(m) display afractional portion of an entire video image, such that the sub-displayelements 302(a)-302(m) cooperate to display one or more combined imagesor information.

In one embodiment, bellows 528 or other elements may be use to mask orhide the space below or between each sub-display 302(a)-302(m) and theunderlying support 304 when the sub-displays 302(a)-302(m) are raised.The bellows 528 might comprise, for example, pleated fabric or othermaterial which can be extended upwardly as each sub-display302(a)-302(m) is rotated outwardly from the support 304, and whichcollapses when the sub-displays 302(a)-302(m) are collapsed back totheir flat, display position.

Connectors (not shown) or other communication links (which could also bewireless) allow data associated with a video input signal to communicateacross or to each sub-display element 302(a)-302(m) so that one or moreimages (static or moving images), including a fully contiguous image,may be presented. Upon re-positioning of the sub-display elements302(a)-302(m) to the staircase 402 position, a switch (not shown) mayterminate the video signal thereby preventing further display in each ofthe sub-display elements 302(a)-(m). In another embodiment, there is noswitch or an optional switch so that video display may remain presentwithin each sub-display element even while primarily functioning as astaircase.

In another embodiment, the controller could send instructions to theactuator mechanism 514 as to when the electronic display 302 is to beconverted to the staircase 402. Concurrently with such instructions, thecontroller could provide additional instructions to re-orient theelectronic display 302 to the require orientation needed for thestaircase 402. Thus, while the actuator mechanism 514 is rotating thesub-display elements 302(a)-302(m) to reposition the sub-displayelements for use as individual steps 526, the mount 324 is moving itsvarious member arms to place the staircase 402 in proper position forease of ascent and descent by a person 404. It will be appreciated thatin a preferred embodiment, regardless of the position or orientation ofthe convertible display, when the display is used as a staircase, thefaces of those sub-display elements or panels 302(a)-302(m) which arerotated are preferably located in generally horizontal planes forsupporting a user (e.g. if the convertible display is oriented at 45degrees relative to a generally horizontal support surface or theground, then the sub-display elements would be rotated outwardly byabout 45 degrees so that the faces thereof would be generallyhorizontal; if the display were oriented at 30 degrees relative to agenerally horizontal supporting surface then the sub-display elementswould be rotated outwardly by about 30 degrees so that the faces thereofwould be generally horizontal, etc.)

In yet another embodiment, multiple convertible displays could beattached to multiple mounts 324. The use of multiple electronic displays302 to multiple mounts 324 has been described herein. However,programmed changes to the convertible displays may occur whereby one ofthe convertible displays is converted to a staircase 402 in acoordinated manner with the convertible displays that remain positionedas electronic displays 302. Further programmed changes may occur suchthat the one or more convertible displays positioned as a staircase 402may convert back to an electronic display 302 and vice versa. This couldoccur while a person or performer was coordinating their movements inassociation with the changes to the convertible displays.

In a further embodiment, two or more convertible displays could be usedin combination to establish a combined staircase 402 that ascends to agreater height or lower depth than that which could otherwise beachieved with only one convertible display mounted to one mount 324.Alternatively, a combination of staircases 402 may establish alternatingspans of ascent and descent. These combination staircases 402 couldfurther be combined with electronic displays 302 in any variety ofcombinations.

In another embodiment, the electronic controller of the mount 324 couldcause the convertible display when functioning as a staircase 402 to beused as a lift to further increase the height in which a person couldascend (e.g. the controller may jointly or cooperatively control theconfiguration of the convertible display and its position or orientationvia the robotic mount). Thus, the while a person 404 is ascending orstanding still on the staircase 402, the robotic arm(s) could move themount in a vertical direction thereby raising the staircase heightsbeyond the height that otherwise would have been obtained by reachingthe highest step of the staircase while the mount remained at rest.These features might have best application to move a person from thefloor to a location that would have been otherwise unattainable from thefloor position through the limited vertical length of the staircase 402.Additionally, the electronic controller could cause the angle of thestaircase 402, as measured by the support panel 304, to increaserelative to the floor thereby further increasing the attainable height.

It will be appreciated that not all of the sub-displays 302(a)-302(m)need to be movable. For example, depending upon the size or height ofthe sub-displays 302(a)-302(m), every other sub-display 302(a)-302(m)might be movable. In such a situation, one or more sub-display elementsor panels which are between raised panels may comprise the step “rise”,wherein the rise between adjacent raised sub-display elements or panels302(a)-302(m) may still be acceptable for use as stairs.

Of course, one or more convertible displays may be utilized withoutrobotic mounts. For example, a convertible display could be fixedlymounted (i.e. position in a single location). In a preferred embodiment,however, the convertible display is associated with a robotic mountwhich allows the position of the entire robotic display to be changed.

In accordance with the invention, a robotic mount is advantageouslyconfigured to move one or more entertainment elements, preferably inthree-dimensions. The entertainment elements may thus be “animated”,providing a much higher level of entertainment value. For example, themovement of one or more video displays adds entertainment value to theinformation or images displayed by the one or more video displays.Likewise, the movement of one or more video projectors allows thelocation of projected images to change, thus adding excitement to theimages themselves. Similarly, the movement of a staircase may be used toentertain observers or riders of the staircase. Further, having aconvertible display provides dual functionality of an electronic displayand a staircase and provides the ability to have these functionsinteract to provide further entertainment value.

It will be understood that the above described arrangements of apparatusand the method there from are merely illustrative of applications of theprinciples of this invention and many other embodiments andmodifications may be made without departing from the spirit and scope ofthe invention as defined in the claims.
